Winter Haven, Florida -- Winter Haven Police say they have arrested one man, and are looking for another, who used the popular online classified advertisement website "Craigslist" to violently rob two unsuspecting victims.

Police say it happened like this: On April 23 at approximately 6:40 p.m., Jamar Octavious Lynch and Javarius Antwane Samuel met the two victims, who had posted a 1997 Yamaha Banshee Twin ATV for sale on Craigslist.

The suspects instructed the victims, Russell Myers and Ryan Snyder from Sarasota, to meet on Palm Dr. NE in Winter Haven.

When the victims arrived, they were met by Javarious Samuel who escorted them to Lake Maude Park in Winter Haven.

Samuel told the victims he was waiting for his cousin to bring the money for the ATV.

When Jamar Lynch arrived, both Samuel and Lynch attacked victim Myers, punching him in the face. At the same time, Snyder jumped on the ATV in an attempt to start the vehicle. Lynch indicated to the victims that he "was packing" implying that he had a weapon.

Samuel then grabbed Snyder pulling him off the ATV and fled on the ATV. Lynch left in a maroon Saturn with a white stripe, which was later located in Haines City.

Warrants were obtained for both Lynch and Samuel. On April 26, Lynch was arrested and booked into the Polk County Jail for Robbery.

The warrant obtained for Samuel is for robbery, use of electronic communication to facilitate a felony and felony battery.

Samuel is still at large and Police are asking the public to contact Crime Stoppers at 1-800-226-TIPS (8477) with any information. Callers can remain anonymous and could be eligible for a CASH reward.
